Another solution for getting Ultimatic keying "inside" a K2 would be the PK4 keyer from Jackson Harbor Press. It's very small, only 1" x 1.5". Jackson Harbor's contest keyer, the Island Keyer II, also supports Ultimatic. Both of these keyers are available directly from Jackson Harbor Press at:
I haven't tried either one of these keyers, but I do have the older PK3 (inside my Palm Radio Code Cube) and like it. Unfortunately, it doesn't do Ultimatic.
